And how can we say we can't get some of his designs
to fly given that many aircraft these days aren't statically
stable anyway.
It's not a matter of static stability... it's a matter of basic aerodynamics, structures, propulsion, pressurization, other details. His fighter has the cockpit stuck way up on a forward fin. Why? It confers no advantages, but makes the plane heavier, weaker, and will batter the crap out of the pilot during maneuvers. His business jet has *triangular* windows, as well as terrible forward vision for the pilots. His "mega passenger aircraft" seems to not pay any attention to the need to generate lift at low speed, and has a structurally hideus outer mold line, requiring massive internal bracing for pressurization, as well as being about as aerodynamic as a Trabant. His forward swept propellors seem to have no basis in reality whatsoever; even made from solid carbon fiber, they'd fly the frak apart under centrifugal force once spun up. His SSTO for NASA shows no internal propellant volume, just a whole hell of a lot of wing area for no good reason... wings that require spars of compound curvature. His two-stage aerospaceplane is so goofy it's not even *wrong.* His Mach 5 aircraft defies logic both in terms of aerodynamics and structure.
Basically he's a grade-school kid doodling neato-kean scribbles, but he somehow convinces people to give him money to make large models of 'em.
Bah.
So these things were not designed functionally as aircraft of course, but they are fun to look
at for me (OK - not all are), but they also give me ideas. I think they can inspire one to design
a new real aircraft.

So I look at this and say, hmmm, possibly the empennage and cockpit all together, and
also all forward. That's interesting to think about.
Also reminds me a bit of the Nord Griffon, and Lippisch LP-13a (cockpit in vertical tail).
That cockpit/empenage really sticks up due to that mounting arm from the main fuselage.
Perhaps it could attach to other fuselages of unmanned vehicles and provide adequate
clearance for forward visibility due to the mounting arm, turning them into manned
vehicles.
What if that arm is a control arm - and what if that arm can rotate the cockpit
through all three axis so that the acceleration vector always goes through the
pilot at the most beneficial place?
Also, nose can possibly interact with the main wing for positive effect (didn't parasol wing
have such an effect - maybe not - I need to go check it out.) Should the cockpit be able
to rotate below the fuselage? Is that better?
Underside vertical stabilizers also act as landing gear. They don't retract. Looks like maybe
a lighter and simpler retraction mechanism than normal.
... And on and on. I actually had many more ideas but this illustrates the process.
So I believe one can get some interesting ideas from this model.

This thing looks like it has lots of volume. Like a Zeppelin. I wonder if this thing could also possibly be a rigid airship and could get some
slow speed lift from that. Also structural strength by gas pressurization from inside maybe? Also an airplane too. Need to check it out!

This one I actually like a lot. I'll bet we could easily fix it. I like the C-130 like view the pilot has. Maybe the canard is all wrong anyway.

I really haven't looked at these too much, but this sounds possiby cool! Blades that open like flowers when they spin up?
I wonder if this could actually be useful as well as cool? I expect someone may have looked at this before.
Anyway, interesting ideas for evenings of enjoyable design fun.
Maybe it won't work out, but maybe something will, and you never know what other idea you may get in the process!
